Hi @orangeSi! I suspect you need to add a Seq path to LD_LIBRARY_PATH. Try export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ubuntu/.seq/lib/seq

[orangeSi]

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ubuntu/.seq/lib/seq

yes, it works! Thanks!

I used https://seq-lang.org/install.sh to install seq, so if add a notation add export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/.seq/lib/seq to ~/.bashrc to the install.sh, will be better for the newbie.

You're welcome. Thanks for the feedback. We want to make the installation process as smooth as possible.
